(13452 Winthrope St., Santa Ana, Calif. 92705) Filed Ian. 29, 1963, Ser. No. 254,615 2 Claims. (Cl. 340-164) The invention relates to improvements in an electrical combination selection system, the object of the improvements being the positive identification of a specific code by permitting the combination selector to select the required code and by a reciprocal code sele-ctor circuit disapprove and exclude all other codes excepting the required code. Likewise, a system in which sets of acceptable codes may be selected, all other sets simultaneously excluded. The invention also relates to a novel manner in setting up receiver and transmitter units to the same code and even though the code thus set up is not known by the person setting up such code the combination of receiver and transmitter working together permits the electrical combination selector system to respond to the c-ode set up by the random code mechanism.

One form of the invention is illustrated in the accompanying drawing in which:

The push button electrical combination selector mechanism, FIGURE 1 is manually operated by sequentially operating the aforementioned push buttons. Correct code yield is achieved by operating push buttons 7-17, 4-14, 5-15 in sequence. When movable push button k contact 17 is operated so that it momentarily cooperates with and makes electrical contact with stationary push button contact 7, direct current flows from direct current power input means 99, through said cooperating contacts 7-17, through cable harness 169, through contact 27 cooperating with selector arm 96 of coding switch 163 and at this point branches off into two branches', one branch current flowing in direction of low forward resistance through diode 91 into one side of relay 155 and then into ground return of direct current power input means 100, thus energizing relay 155 and pulling open normally cooperating contact pair 156- 157 disabling alarm indicator 159; the other branch current flowing in direction of low forward resistance through diode 93 into coil of relay 107 and into ground return of direct current power input means 100, thus energizing relay 107, pulling closed contact pair 108 and 109 so that they cooperate with ea-ch other and thus hold relay coil 107 energized, by virtue of electrical energy from hot side of direct current input power means 99 being present on contact 109, pulling contact pair 112 and 1134 together so they cooperate with each other, pulling contact pair 116 and 117 together so they cooperate with each other, pulling contact pair -111 together so they cooperate with each other and enable a closed electrical path to relay coil 127, opening normally cooperating contact pair 114 and 115 to disable the operation of relay 120, and operate contact pair 118-119 so that they cooperate with each other 4causing relay coil 138 to be energized since current will flow from hot side of direct current power input means 99 through the momentarily cooperating push-button contact pair 7-17, in forward direction through diode 57 via cable harness 169 to cooperating contacts 77 and 102 of inverse coding switch 167, through normally cooperating contact pair132-133, through contact pair 118-119 which now cooperate with each other, through relay coil 138, and to ground return of direct current input power means 100 thusly electrically energizing relay 138, causing contact pair 139-140 to cooperate with each other and normally closed cooperating contact pair 141-142 to open and cease to cooperate with each other; simultaneously power from the hot side of direct current input power means 99 ilows through normally cooperating contact pair 161-162 through relay coil 160, through the now cooperating contact pair 116-117 to ground return direct current input power means 100 to energize time delay relay 160 which will remain energized for the duration of a specic preset period of time to permit the rest of the code to be injected and subsequent to such period -of time will automatically deenergize itself thus resetting above mentioned components to their normal positions as shown in FIGURE l.

When movable push button contact 14 is operated so that it momentarily cooperates with and makes electrical Contact with stationary push button contact 4, direct current ows from direct current input power means 99 through cooperating contact pair 161-162, through cable harness 169, through contact 34 cooperating with selector arm 97 of coding switch 1 64 and at this point branches olf into two branches; one branch current flowing in direction of low forward resistance through diode 92 into one side of relay coil 155 and then into ground return of direct current power input means 100, thus maintaining relay coil 155 in the previously energized state and maintaining contact pair 156-157 in an open or noncooperating state, thereby maintaining alarm indicator 159 in a disabled or non-operating state; the other branch current iowing in direction of low forward resistance through diode 94, through the now cooperating contact pairy 110-111 into coil of relay 127 and into ground return of direct current power input means 100, thus energizing coil 127, pulling closed contact pair 128 and 129 so that they cooperate with each other and thus hold relay coil 127 energized by virtue of electrical energy from the hot side of the direct current power input means 99 being present on contact 129, pulling contact pair 130 and 131 together so they cooperate with each other, pulling contact pair 134 and' 135 together so they cooperate with each other and enable a closed electrical path to relay coil 143, open normally cooperating contacts 132 and 133 so that previously energized relay coil 138 will be deenergized and released thus opening cooperating contact pair 139 and 140 and returning to normal contact pair 141 and 142 so that they again cooperate with each other, and pulling together of contact pair 136 and 137 so they cooperate with each other thus enabling relay coil 15G; simultaneously current will flow in a forward direction through diode 54 via cable harness 169 to cooperating contacts 34 and 103 of the inverse coding switch 168, through normally cooperating contact pair 148-149, through contact pair 136-137 which now cooperate with each other, through relay coil 150, and to ground return of direct current input power means 100 thusly electrically energizing relay 150, causing contact pair 151-152 to cooperate with each other and normally closed cooperating contact pair 153-154 to open and cease to cooperate with each other.

When movable push button contact 15 is operated so that it momentarily cooperates with and makes electrical contact with stationary push button contact 5, direct current ilows from direct current input power means 99, through cable harness 169, through contact 45 cooperating with selector arm 98 of coding switch 165, in direction of low forward resistance of diode 95, through the now cooperating contacts 134 and 135 into one side of relay coil 143 the other side of relay coil 143 being connected to ground return of direct current power input means 100 thusly energizing relay 143, causing contact pair 144 and 145 to cooperate with each other thus providing holding power to relay 143 inasmuch as the hot side of direct current input power means 99 is connected to said contact 145 through cooperating contact pair 161 and 162, pulling normally cooperating contact pair 148-149 open so that they cease to cooperate with each other thus breaking the electrical path to relay coil 150 and thereby disabling relay 150 which in turn opens previously cooperating contact pair 151 and 152 so that they cease to cooperate with each other and thereby remove the hot side of direct current input power means 99 from alarm indicator 159 thus disabling said alarm indicator 159, while contact pair 153 and 154 previously caused to cease to cooperate are restored to their normally closed state so that they again cooperate with each other, while contact pair 146 and 147 are pulled together due to electrical energizing of relay 143 so they cooperate with each other and make electrical connection to one side of code acceptance device 158 the other side of said device 158 being electrically connected to ground return of direct current power input means 100, permitting code acceptance device 158 to receive electrical power and hence to operate.

When the push button electrical combination selector mechanism, FIGURE l, is manually operated by pushing any of the aforementioned push buttons for a code digit other than the aforementioned preset digits or when a digit is operated out-of-sequence, current will flow from the hot side of direct current input power means 99 through cooperating contact pair 161 and 162, through cable harness 169, through the forward direction of the diodes 51, 52, 53, 54, 55, 56, 58, 59, 60 causing an electrical current to flow through contacts 61, 62, 63, 64, 65, 66, 68, 69, 70 which cooperate with selector arm 101 of inverse coding switch 166, causing a current to flow through normally closed and cooperating contact pair 114 and 115 into one side of relay coil 120 the other side of said relay coil being connected to the ground return of direct current input power means 100, thereby electrically energizing relay 120, causing contact pair and 126 to cooperate with each other which causes power to be applied to time delay relay through cooperating contacts 161 and 162 and cooperating contacts 125 and 126, causes contacts 121 and 122 to cooperate with each other and make electrical connection to alarm indicator 159 by virtue of current flow through said alarm indicator 159 through normally cooperating contact pair 156 and 157, and energizing said alarm indicator 159, and opening cooperating contact pair 123 and 124 so that they cease to cooperate thus opening the electrical path to code acceptance device 158, preventing said code acceptance device 158 from being electrically energized. The circuit is automatically restored to its normal position as in FIGURE l, when the preset delay time of time delay relay 160 has elapsed. Should the rst digit be correctly selected and the second digit be irnproper or out of sequence, by operating of aforementioned push buttons, direct current will flow through diodes 51, 52, 53, 55, 56, 57, 58, 59, 60 through contacts 71, 72, 73, 75, 76, 77, 78, 79, S0 cooperating with selector arm 102 of inverse coding switch 167 through normally cooperating contacts 132 and 133 and now cooperating contacts 118 and 119 providing an electrical path to relay coil 138 thus energizing relay coil 138, causing contact pair 139 and 140 to cooperate with each other and causing power to be applied to alarm indicator 159 through normally cooperating contact pair 156 and 157, electrically energizing said alarm indicator 159, and holding said alarm indicator 159 energized for the specific period of time that time delay relay 160 remains energized, said time delay relay 160 having previously been electrically energized through flow of current through cooperating contact pairs 161 and 162 in series with relay coil 166 which is in series with the previously activated relay coil 107 which had caused Contact pair 116 and 117 to cooperate with'each other thusly holding energized said time delay relay 160 for a specic period of time. At the same time normally cooperating contact pair 141 and 142 is opened thus ceasing to cooperate with each other due to the energizing of relay 138, causing the electrical path to the code acceptance device 158 to be Open and electrically discontinuous. Should the rst and second digits be correctly selected and the third digit be incorrect, by operating the aforementioned push buttons, direct current will flow through diodes 51, 52, 53, 54, 56, 57, 58, 59, 60 through contacts 81, 82, S3, 84, 86, 87, 88, 89, 90 cooperating with selector arm 103 of inverse coding switch 163, through normally cooperating contacts 148 and 149, and now cooperating contacts 136 and 137 providing an electrical path to relay coil 150 thus energizing relay coil 150, causing contact pair 151 and 152 to cooperate with each other and causing power to he applied to alarm indicator 159 through normally cooperating contact pair 156 and 157, electrically energizing said alarm indicator 159, and holding said alarm indicator 159 energized for the specific period of time that time delay relay 160 remains energized, said time delay relay 160 having previously been electrically energized through flow of current through cooperating contact pair 161 and 162 in series with relay coil 160 which is in series with the previously activated relay coil 107 which had caused contact pair 116 and 117 to cooperate with each other thusly holding energized said time delay relay 160 for a specic period of time. At the same time normally cooperating contact pair 153 and 154 is opened thus ceasing to cooperate with each other due to the energizing of relay 150, causing the electrical path to the code acceptance device 158 to be open and electrically discontinuous.
